ECHO Process Instrumentation, Inc. products

Capacitance Point Level Switch for Liquids and Solids. The ECHO CapSwitch 500 is a reliable capacitance level switch that does not have any moving parts. The state of the art sensing technology is impulse RF admittance measurement with an active guard. This provides excellent level detection while being insensitive to material buildup. Capacitive level technology can be used for liquids, slurries, powders and bulk materials. Also, the CapSwitch 500 can be used for liquid interface applications to detect the level of two immiscible liquids that have different dielectric constants such as oil and water.

he Ultrasonic Point Level System 416X Series is an ideal solution for detecting liquid in compact spaces. With integrated electronics it is a direct replacement for Float Switches, Capacitance and Optical Detectors. The GS 416X detects liquid irrespective of change in density color, dielectric constant or viscosity. The GS 416X does not require calibration or periodic maintenance. The sensor is constructed in 316 SS and is available in lengths of up to 99”. ECHO can provide the GS 416X in a variety of engineered plastics to obtain the ideal corrosion resistance in process vessels.
